To all whom it may concern:

Be it known that I, CHESTER W. TULLAB, citizen of the United States,residin at Detroit, county of ,VVayne, State of Michigan, have inventeda certain new and useful Improvements in Envelops, and declare thefoltion of the same, such as will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

sealing of the flap.

My invention relates to envelops and more particularly to the class ofenvelops employed for mailing circulars, catalogues and thelike in whichthe flap of the envelop is left unsealed to effect a saving in postalrates.

One object of, my invention is to provide means adapted to protect thecontents of the envelop against accidental discharge therefrom but whichdoes not necessitate the A further object of the invention is to providefor the protection of the contents of the envelop without adding, ormaterially adding to the cost of manufacture as envelops are ordinarilyconstructed.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood'thatchanges may be made inthe precise embodiment of the invention herein disclosed'withoutdeparting from the spirit of the same.

In the accompanying drawings forming part of this specification Figure lis a rear elevation of an envelop having a side opening embodying myinvention,

. Referring now to the letters of reference placed upon the drawings A,denotes an envelop, B, the usual side or end flap, slitted as at B toreceive'an engag ing tongue 0, integralwith the back wall ofthe envelop,If desired an envelop may be constructed with a plural number of en aging tongues C, as indicated in Fig. 3 o the drawings, thus preventingthe loss of any relatively small articles that may be inclosed in theenvelop.

To provide the engaging tongue C, the portions formin the back of theenvelop may be constructe so as to overlap, as indicated in Figs. 4, 6,and 8 of the drawing. 1

Having indicated the several parts by reference letters, it will be seenthat upon filling the envelop with the circular matter to be mailed, thesender turns in the flaps so as for increased use-or wear of to overlapthe contents of the envelop, and 1 then inserts the engaging tongue 0 inthe slit B of the flap. The mouth of-the envelop is thus secured againstgaping, thereby protecting. its contents from accidental disc arge. I

It will be noted that practically no ad- .ditional expense'is added bymy invention to the cost of manufacturing envelops. The engaging tongueis constructed from that portion of the sheet usually cut away in formmgthe back ,wall of the envelop; while a saving is 'eflected byeliminating the 'cost of clips or other engaging devices together withthe loss of time required for installing these devices upon theenvelops.

Having thus described my invention what 'I claim is An envelop having arelatively narrow unsealed closurefiap disposed loosely against the bodyof the envelop and provided with a slit, the slit in the flap beingdisposed adjacent one edge of the envelop body, andthe rear Wall of theenvelop having a relatively short projecting ungumrned tongue adapted toextend through said slit and be wholly confined Within the envelop andfree of either the closure flap or the body of the envelop, the contentsof the envelop adapted to hold the tongue against the closurefiap,thereby preventing displacement of the tongue.
